A religious symbol is an iconic representation intended to represent a specific religion, or a specific concept within a given religion.
Religious symbols have been used in the military in many different countries, such as the United States military chaplain symbols. Similarly, the United States Department of Veterans Affairs emblems for headstones and markers recognise 57 symbols (including a number of symbols expressing non-religiosity).
Symbolic representation of a specific religious tradition is useful in a society with religious pluralism, as was the case in the Roman Empire, and again in modern multiculturalism.
